Basil is very chill sensitive! It does best stored at 50 degrees F.
In The Refrigerator Most people do not have a refrigerator with a special area that maintains this temperature. So - if you would like to refrigerate it, we suggest storing it in the warmest part of your refrigerator (generally the door) in a plastic bag or container - make sure the basil is relatively dry before sealing up the container.
On The Counter If your room temperature doesn’t exceed 68 degrees, basil can be stored at room temp.
A Counter Alternative Slice the stems on a diagonal, put them in a tall jar or other container with water in the bottom, cover the jar with a plastic bag or plastic wrap and rubber band the plastic around it. Put in a cool place in your kitchen (50 degrees).
In The Freezer Basil can also be frozen for later use. Although it loses its bright green color, frozen basil still has great flavor and works well in sauces.
